hi all some suggestion where to buy ip address?

contact your hosting provider
you can order from them.
since they have to get an IP which their router can handle....

strange but true: my provider has finish them, waiting to buy a new class of ip's (that is what they sayd ).
The problem is don't want wait more...

Sorry to say

but you have 2 options

1) Wait
2) Move to a new ISP
